After wanting greater flow / turnover - I replaced my Eheim Pro 3 350 (rated at 1050lph) today with an Eheim 3e 700 (rated at 1850lph) - the flow rate is really disappointing, even set all the way to maximum, it's practically producing the same flow as the 350 it replaced.
Any other 700 owners care to share their thoughts?
